MACHINE FOR CUTTING- GREEN CORN FROM THE COB.

Specification of Letters Patent.

Patented Nov. 15, 1910.

Application filed. may 4, 1908. Serial No. 430,733.

T 0 all whom it may concern:

Be it known that we, SAMUEL E. MORRAL and IVILLIAM W. MoRRAL, citizensof the United States, residing at Morral, in the county of Marion andState of Ohio, have invented a certain new and useful Improvement inMachines for Cutting Green Corn from the Cob, of which the following isa specification.

This invention relates to the class of machines shown in Letters Patentsof the United States No. 679,156, dated July 23, 1901, and No. 787,585,dated April 18, 1905.

The chief object of the present invention is to make improvements insuch machines whereby the kernels of corn are more finely divided so asto render them more economically cooked and palatable and digestible.

Another object of the invention is an improved construction of knife forcutting the corn.

The invention consists in the details of construction hereinafterdescribed and then pointed out in the claims appended hereto.

In the accompanying drawings-Figure 1 is a view in elevation looking atthe right hand side of the machine with parts broken out; Fig. 2 is atop plan view of the front or feeding end only of the machine with partsremoved; Fig. 3 illustrates in side elevation the improved cuttingdevices; Fig. 4c is a plan view of the same; Fig. 5 is an end view of apair of the horizontal cutters, and Fig. 6 is a fragmentary sectionshowing the form of the flange on the feed chain guard.

In the present machine the general construction is substantially thesame as in the former patents herein referred to, that is to say theframe 1, the toothed feed chains 5, the horizontal guides, the verticalguides, the horizontal scrapers 11, the vertical scrapers 12, and thefeed wheels 13 on the shafts 14 are all substantially as shown in saidformer patents and operate or are operated in substantially the same wayand need not, therefore, be here again particularly described. In thepresent case, however, we mount in tandem on each shank of thehorizontal guides 7 a pair of horizontal cutters 7 b and 7 arranged sothat there shall be one pair vertically considered in advance of theother. The cutters cut in lines parallel to the axis of the ear. Theforward pair 7* of such cutters are arranged and secured to cut thekernels in lines the more remote from the axis of the ear and not asclose as possible to the cob but only about, say half way of their depthand the rear or succeeding pair 7 are arranged and secured to cut theremainder of the thus cut kernels or as close to the cob as desired. Inother words the cutting edges of the horizontal pairs of cutters lie inarcs substantially parallel to each other. The kernels are thus dividedtransversely of their depth, and roughly speaking the product is twiceas fine as where a single pair of cutters is employed to cut in thefirst instance as close as possible to the cob. It will be understood,however, that, as shown, the pairs of cutters 7 and 7 remove the cornfrom the upper and lower sides only of the ear. To perform a similaroperation on the sides of the cars we employ two pairs of cuttersarranged one in advance of the other, as seen at 8 and 8, said cuttersbeing arranged in conjunction with guides 8 and 8* respectively forproperly directing the ear to the cutters. The forward pair of verticalcutters 8 are arranged and secured to out about, say half way throughthe kernels, and the rear or succeeding pair 8 are arranged and securedto cut the remainder of such kernels or as close to the cob as desired.After the cob is carried beyond the pair of cutters 8 it is fed throughthe scrapers to remove small pieces that may yet remain, substantiallyas set forth in said former patents.

In machines of this kind the feed chains 5 at the front of the machineare run with considerable speed, and, as a consequence many kernels ofcorn and fluids or juices thereto belonging were scattered about thefront of the machine. We, therefore, provide the plates 2 on which saidchains run, said plates extending beyond the path of the points of thespurs of the feed chains at the front of the machine and provided withflanges 2 that inclose the feed chain at the front of the machine andprevent the kernels and juices taken by the feed chain from beingscattered on the floor in front of the machine. Instead said kernels andjuices are allowed to drop through spaces as at 21 into a receptaclesuitably supported under the machine below said spaces and the cutters.

The improved form of cutter, as best shown in Fig. 5, consists inplacing the shank so as to rise or extend from or near the side edge ofthe cutter, as seen at 7 In the instance shown the shank rises from theside of the knife in a plane at right angles to a chord subteriding theare of the knife.

become entangled With and accumulate on the shank. Time and trouble aretherefore saved in keeping the machine free of obstructions to thepassage of the ears therethrough.

hat We claim and desire to secure by Letters Patent is: I '1. In amachine for cutting green corn from the cob, the combination with meansfor automatically feeding the car into the machine in the direction ofthe longitudinal axis of the ear, a pair of opposin gly arranged guidesto act on different sides of the ear, pair of cutters having theircutting edges parallel to each other and said cutters being in tandemconnection with each of said guides, said cutters also arranged to cutin a direction parallel to the axis of the ear and at different sides ofthe ear, the forward of the cutters in each "pair being located :to cutin lines more remote from the axis of the car than the lines of the cutof the rear cutter, whereby portions only of the kernels of the car areremoved by the forward cutter of each 'pair and the "remainder of "thesevered kernels are removed by the rear cutter of each pair,substantially "as described.

'2. In a machine for cutting green corn from the cob, the combinationwith means for ai'itomati'ca lly feeding the ear into the machine thedirection'o'f the longitudinal axis of the car, a pair of opposinglyarranged guides to act on two opposite sides of the ear, a pair'o'f'cu'tters having their cutting edges parallel to each other and saidcutters being in tandem connection with each of said guides, saidcutters also ar- With this construction of knife the, silks of the greencorn are not likely "to' ranged to cut in a direction parallel to theaxis of the ear and at opposite sides ofthe ear, the forward of thecutters in each pair being located to cut in lines more remote from theaxis of the car than the lines of the cut of the rear cutter, and twopairs of similarly arranged cutters in the machine in rear of the firstmentioned cutters to similarly cut kernels in lines left uncut by saidfirst mentioned cutters whereby port-ions only'of the kernels of the carare removed by the forward cutter of each pair and the remainder of thesevered kernels are removed by the rear cutter of each pair of cutters,substantially as described. i

3. In a machine for cutting green corn from the cob, a cutter consistingof a curved blade having one of its curved edges formed as thecuttingedge, said blade provided with an attaching shank projecting fromone of the side or non-cutting edges of the blade and in a directionapproximately at right angles to a chord subtending the aforesaid curvedcutting edge.

4. In a machine for cutting green corn from the cob, the combinationwith a guide having a shank, 'ofa pair of cutters secured to said shankone arranged in advance of and beyond the other, each of said cuttersconsisting of a transversely curved blade having one of its curved edgesconstituting the cutting edge, and an attaching shank projecting fromone of the side or non-cutting edges of the blade and in a directionapproximately at right angles to a chord subtending the aforesaid curvedcutting edge.
